Enhanced Fatigue Resistance

Cold rolling on the thread roots of every connection is necessary to increase the connection’s ability to resist failure from cyclic stresses on the thread roots when stiffer heavy weight drill pipe undergoes repeated severe tensile and compressive stresses at drilling operation.

Surface Protection

DP-Master can supply heavy weight drill pipe with any market available internal plastic coating. The coating forms a protective layer in the pipe ID to prevent corrosion and thus extend the life span of the pipe in the drilling environment.
